I'm running iOS 10.3 simulator on latest 2017 15 inch maxed out macbook pro and the performance is terrible. FPS are noticeably low even when switching tabs on home screen or using preinstalled apps (without any of my apps installed). This is a bit disappointing. I'm sure that Slow Animations setting (⌘T) is not enabled.
I'm running Xcode Version 8.3.3 and macOS 10.12.5. The same thing hapens for Xcode 9 beta.
